Our Verdict

The Asus Zenfone Max Pro can take on the best in the market with ease. Like most Asus phones, the spec-sheet is maxed out with the best mid-range hardware. That includes latest stock Android and a 5,000mAh battery, two features which solve the biggest pain points people tend to have when making a purchase at that price range. The phone even manages to take on the formidable Redmi Note 5 Pro, save for the imaging prowess, but the pros easily outweigh the cons. In all, it’s always good to have a choice of clean stock UI without compromising on the performance.

Asus Zenfone Max Pro M1 64GB: Detailed Review

The mid-range market is now dominated by Xiaomi. There’s one Redmi phone for every price point in that segment and the consumer is essentially spoilt for choice. However, Redmi phones are notorious for getting sold out in seconds. Getting your hands on one is a matter of pure luck. But then again, we have always recommended our readers to wait and try their luck because no other phonemaker has been able to match up to the quality Xiaomi assures in its products. That is, until now.

The Asus Zenfone Max Pro is a breath of fresh air in a market that is otherwise inundated with Xiaomi phones. Asus’ offering matches Xiaomi’s most premium mid-range offering feature-by-feature and for the most part, can be considered an equal. Except, the Max Pro runs on stock Android UI while the Redmi Note 5 Pro is of course powered by MIUI. There’s nothing wrong with using MIUI, but there’s a certain simplicity and comfort in using stock Android. It’s familiar to anyone who has used an Android device and is efficient enough to not tax the processor. Considering how the UI is the most frequent aspect of the phone a user will interact with, it counts a lot, and in this case, Asus’ choice makes the Zenfone Max Pro a force to reckon with. What’s better is that the phone is much cheaper than the Redmi Note 5 Pro and will be available more easily than the Redmi Note 5 Pro.

The question then remains, did Asus finally crack the formula to make a reliable mid-range phone? With the Zenfone Max Pro, it certainly seems so. It has everything you can ask for at the price — The latest mid-range chipset, tall 18:9 display, dual cameras and a massive 5,000mAh battery. In this review, we find out whether all the features work as advertised, and more importantly, does it make sense to buy this over the Redmi Note 5 Pro? Read on.

Design

Taller displays aren’t new anymore and neither is the metal unibody design most mid-range smartphones like to sport. The Zenfone Max Pro is yet another iteration of the same design philosophy. The display takes up most of the real estate up front while at the back the dual camera module is vertically aligned at the top left corner. The fingerprint sensor is conveniently placed in the center where the finger can easily reach it. The form factor with a thinner display is naturally ergonomic and the rounded corners makes the phone sit plush in the hand.

Like most other mid-range phones, the Zenfone Max Pro also deploys a 2.5D curved glass that bends ever so slightly to meet the metal frame. Asus has polished the rear plate to give a soft matte finish that does tend to get dirty when used with sweaty hands but isn’t a fingerprint magnet. There are two colour variants to choose from — Meteor Silver and Deepsea Black. Both look equally good and you’ll be hard pressed to make a choice. There’s colour-matched polycarbonate antenna lines to enhance network reception.

I particularly liked the fact that the dual camera module is flush with the body and there’s no camera bump, which has become an eyesore in most smartphones. There’s also no need to make a choice between a second SIM card and a microSD card as the phone houses dedicated slots for all three. In the mid-range market, that counts as a lot since most users tend to use a secondary SIM card and rely on expanded storage.

The design of the Zenfone Max Pro isn’t going to get points for being innovative, but it does comes across as well-built and functional. The added heft, thanks to the massive 5,000mAh battery provides a good grip and the minimalist body makes the display the center of attraction.

Display

The Zenfone Max Pro could have been easily lost in a sea of smartphones with an 18:9 display, if not for the superior quality of the panel. Like most other mid-rangers, this too relies on a 6-inch FHD+ IPS LCD panel, housed in a 5.5-inch body. While the idea isn’t as innovative as before, the usefulness remains. There’s less scrolling while browsing the web, while gaming on the widescreen allows for easier controls. Split-screen on the display is particularly useful as the screen gets divided into two equal halves.

For bedtime use, Asus offers a blue-light filter as well as a slider to adjust the colour temperature.

Asus claims to have used Qualcomm’s TruPallette and Ecopix display technology to render a higher contrast ratio of 1500:1, which shows when you watch something on the screen. The blues and the greens look saturated with high contrast while skin tones are made more accurate. It’s still no match for an AMOLED panel though in terms of contrast ratios, but the colour are more vibrant than its closest competitor — The Redmi Note 5 Pro.

Performance and UI

Asus’ choice of using the latest hardware and stock Android will keep this phone in the limelight for some time to come. The Zenfone Max Pro is powered by the Snapdragon 636 chipset, the one introduced by Xiaomi’s Redmi Note 5 Pro in the mid-range segment which effectively blew the competition away.

The 14nm chipset builds on top of the popular and reliable Snapdragon 625, offering a 50 percent jump in performance over its predecessor. That’s possible even after the max clock speed has been reduced to 1.8GHz from 2.0GHz in the SD625. It’s because the SD636 uses Qualcomm’s custom Kryo cores which is also used in the flagship 8-series chipsets, allowing the CPU to provide more power for longer without compromising on battery efficiency.

The benchmark results also narrate the same story. There’s almost a 50 percent jump in AnTuTu score from the Redmi Note 5 (which uses the SD625) while the Redmi Note 5 Pro (which uses the SD636) is almost at par, edging the Zenfone Max Pro out by roughly 50 points. The 3DMark Slingshot score which takes the GPU into account gave identical scores, indicating the graphical prowess of the two phones is at par. The reason why the Redmi Note 5 Pro edges this phone out is because Xiaomi offers 6GB of RAM with the phone while Asus’ offering sticks with 4GB of RAM. There’s also 64GB of onboard storage to boot, which is again expandable.

The Snapdragon 636 on the Zenfone Max Pro also brings support for Bluetooth 4.2 with Qualcomm’s AptX technology for clearer audio over wireless connections. The mono speaker on the phone is quite loud as well, thanks to a built-in NXP amplifier and a 5-magnet speaker. What’s irksome is the positioning of the speaker. Despite being loud, holding the phone horizontally muffles the sound as the hand grips the phone right where the speaker is.

But more than the hardware underneath, the reason the Zenfone Max Pro is such a good performer is because of stock Android. The phone runs on stock Android 8.1 with the February security patch. The lightweight Android, as designed by Google is known to offer minimum interference to performance with a clean and simple user interface. Those upgrading from a Moto G5 or the Mi A1 will feel right at home. There’s hardly any bloatware save for a third-party payment app and Asus promises version updates less than two months after Google pushes it out.

Camera

While the Zenfone Max Pro matches the competition in every other aspect, the camera leaves a lot to be desired. It’s not a bad camera per se, but photos from phones like the Redmi Note 5 Pro has spoilt me. The Zenfone Max Pro features dual cameras at the back — A 13-megapixel primary sensor and a 5-megapixel depth-sensing unit. The camera is placed at the top left corner with a single LED flash right beneath it. The primary camera has an aperture of f/2.2 with 1.0um pixel pitch.

The camera specs are mostly the same as the Redmi Note 5 Pro, which is our best-ranking mid-range phone currently, but the results are not the same. Photos from the Zenfone Max Pro are average, to say the least. That wow factor is missing. Highlights get clipped often and details in the textures isn’t as prominent as the best in the market. It’s still better than most other mid-rangers, but if you’re looking for the absolute best, it’s best to try your luck in getting the Note 5 Pro.

The camera UI on the Zenfone Max Pro is somewhat cluttery and isn’t quite aesthetically pleasing as in other phones by Moto or Xiaomi. Asus deployed Qualcomm’s stock camera app which does offer a range of scenes to choose, as well as filters, but most options like the pro-mode are cluttered inside the settings page, making it a hassle to adjust the settings manually.

Daylight

Any mid-range phones will take decent daytime shots with ample light pouring into the frame. So does the Zenfone Max Pro. You will get well-lit photos which are bright and vibrant. The colour temperature does tend towards the warmer side, but they look aesthetically pleasing regardless. But as I mentioned above, the camera isn’t a match for the Redmi Note 5 Pro. Highlights tend to get overexposed when exposing for the shadows and details are lost in the shadows when trying to prioritise highlights. The dynamic range leaves a lot to be desired.

Indoor

The photos taken indoors highlight the weaknesses of the camera. There’s an ugly glare from the incandescent source of light when taking photos indoors, while close-up shots are somewhat well-lit but aren’t as sharp. The white balance is more accurate though, as compared to the Redmi Note 5 Pro, which is definitely a good thing.

Macro

Close-up shots, taken in daylight will result in well-detailed, sharp macro shots. In the photo below, the details in the flower are well-preserved while the colour of the flower came out a little more saturated, yet not as much as the Redmi Note 5 Pro.

Low-light

The camera on the Zenfone Max Pro isn’t conducive for use in low-light. There’s considerable noise in the photos. The shadows are practically blackened and whatever area is lit is mired in grains. To be frank though, most mid-rangers aren’t capable of good low-light shots and this one is just the same.

Portrait Shots

Bokeh shots are ever so popular now and phones like the Redmi Note 5 Pro and the Mi A1 are known to be masters at it. The Zenfone Max Pro tries hard to match up to that level, but doesn’t quite make it. There’s ample blurring, yes, but the blurring is inconsistent and the portrait comes across as being heavily edited on Snapseed. You also cannot control the amount of blurring, something that Honor phones do provide.

Front Camera

The Zenfone Max Pro sports an 8-megapixel shooter with F/2.0 aperture combined with a soft LED flash. The selfies actually come out well-detailed with the right amount exposure and minimal beauty effects. It can also take portrait selfies and unlike other selfie-centric phones like the Oppo F7, the background isn’t overexposed to make the portrait stand out. The Max Pro manages to do it without clipping the background light.

Battery

One of the highlights of the Zenfone Max Pro is the 5,000mAh battery. Asus has managed to maintain a slim profile despite maxing out the battery capacity. It does help and combined with the power-efficient chipset and stock Android UI, the 5,000mAh battery can easily last the phone over a day and a half. PCMark’s 2.0 Battery test ran for 10 hours 39 minutes which easily converts to over a day of use. One of the main reason to recommend the phone is for the long battery life. Asus also bundles a fast charger with the device that can charge the phone to its full capacity in around 2 hours 30 minutes.

Bottomline

The Asus Zenfone Max Pro may stands particularly because of the superior performance and the choice of stock Android at that price. There are other stock Android phones available at this price as well, but none of them pack so much firepower inside as the Zenfone Max Pro. It performs neck-to-neck with the Redmi Note 5 Pro, but Xiaomi’s offering far better in the camera department. But if you are a stickler for a hassle-free UI, superior performance and long battery life, this is the phone to go for. The fact that it’s also cheaper than the Redmi Note 5 Pro makes it a no-brainer. Also, unlike the Note 5 Pro, this one won’t be sold through flash sales, so availability is not going to be an issue. Combine that with Flipkart’s ‘Complete Mobile Protection’ for Rs 49, and Asus has a winner in its hands. If only the name was a little easier to say.
